Road Conditions Test in Virtual Driving System Based on Cohen-Sutherland Algorithm

Abstract

This paper discusses the methods of improving the efficiency and exactitude of the road conditions test though the modeling test algorithm. It presents the data structure of road model in which double direction data chain can be established. There are two clipping windows, Wout and Wcontour. Wout would eliminate the lines that can’t intersect rapidly. The lines that maybe intersect would be estimated exactly by Wout after coordinates transforming.Thealgorithms of the road conditions testing are proved to be efficacious.
